Voice agent webhooks

Stream conversation events to your backend live, with signed payloads you can verify.

  • Stream conversation events as they happen
  • Signed, verifiable payloads

Definition

Voice agent webhooks stream conversation events to your backend as they happen. Turns, tool calls, and lifecycle events arrive in real time, so your systems react during the call rather than reconciling after it. No polling, no waiting for a batch export.

How it works

You register an endpoint. As a conversation unfolds, the platform posts events to it: the caller spoke, a tool was called, the call ended. Each payload is signed, so your endpoint verifies the signature before acting, confirming the event is genuine and untampered.

What to do with events

Write transcripts to your warehouse, update a CRM record mid-call, trigger fulfillment, or feed live analytics. Because events stream as they happen, your downstream systems stay in step with the conversation.

Verification

Signed payloads are the trust boundary. Your endpoint checks the signature on every event, so a spoofed request cannot drive your workflows. Verify first, then act.

FAQ

Frequently asked questions

What do voice agent webhooks do?
Webhooks stream conversation events from an agent to your backend as they happen: turns, tool calls, and lifecycle events. Your systems react in real time, logging the call, updating a record, or triggering a downstream workflow, without polling for state.
Are the payloads secure?
Yes. Webhook payloads are signed, so your endpoint can verify each event genuinely came from the platform and was not tampered with. You validate the signature before acting on the event.
What can I do with the events?
Anything your backend needs: write the transcript to your data warehouse, update a CRM record mid-call, kick off a fulfillment step, or feed analytics. The events arrive as the conversation unfolds.
